National Police spokesman and MP Mark Mitchell said what happened near a normally quiet beach was “tragic”. “Everyone should be able to go out” without fear of being attacked by a knife, “he added.

St. John New Zealand said five people were injured and four were taken to Auckland Hospital.
Three people have moderate weight and two light.
East Coast Bays MP Erica Stanford said Murrays Bay was a small community that would feel the impact of the attack. “I am sure the police have arrested the person who is interested.”
A Mirangi resident said he saw “enough police” in the area.
“I saw three or four passing by here to Murrays Bay and an ambulance as well,” he said.
Police have diverted the area around the incident and are urging people to avoid the area.
